-3 x 13 super easy its all about negative and positives sign
We Know, speed = Distance / Time
Here, Distance = 2748 miles
Time = 6 hours
Substitute their values in to the expression,
Speed = 2748 / 6 = 458 Miles / Hour
So, the speed would be: 458 miles/hour
Hope this helps!
Can u pls show the picture so that I can solve the problem?
Thx

Answer: The answer is (d) It is an irrational number.
Step-by-step explanation: Given formula for circumference of a circle is

where 'd' is the length of the diameter and a rational number.
We are to choose one of the given four options for the circumference 'c' of the circle.
We know that the circumference of a circle with diameter 'd' is given by

Comparing this with the given equation, we get

Now, the product of a rational and an irrational number is again irrational, so 'r × d' will be an irrational number.
Hence, the circumference, c = rd is irrational.
Thus, the correct option is (d) It is an irrational number.
